Vintage Burst Parts vs Historic Burst parts?

What were the posts for the ABR 1 and the Aluminum tailpiece made of in real vintage bursts?

What are the posts for the ABR 1 and aluminum tailpiece made of now on Historic bursts?

they use different materials, post length and bushings size for the tailpiece.

The historic parts basically look the same but aren't................

There are sources for originals but they are expensive and require mods to the Reissues to use them.

I know they aren't the same, I am asking if anyone knows what metals made the vintage ones, and what metals made the historics. I am also not installing them into a historic, for I don't own one.

Just curious on metal composition.

steel

if you are going to take the time to respond...might as well make it useful...

steel to which? or steel to both?

I am also nearly positive the vintage ones were not steel unless they were plated.

lp_junkie · 09-09-2009, 03:34 PM

the originals are of a different steel than the newer parts. I think the thing that really matters is the fact that the posts were longer not really the material as much.

I had an article that actually showed the parts side by side, listing differences.

The threaded posts for the ABR-1 on my 59 have no bushings. They are screwed directly into drilled holes into the top. Don't know for sure about the tailpiece bushings. I hope I never have to find out.

Tailpiece posts go into straight knurled steel bushings on historics and real ones. The lengths might vary, but talk of different steels sounding particularly different from one another is probably over-egging things. The machining of the threads would make a lot more difference acoustically. All steels have the same approximate density and elastic modulus. The hardness and tensile strength make no difference to acoustic waves.

Aluminum Tailpieces are made of aluminum

50's tailpiece bushings were steel , sometimes galvanized and sometimes uncoated altogether, and the reissues are steel but the reissue bushings have a lead content which the originals didn't.
The original tailpiece studs are nickel plated steel and the reissues are nickel plated brass.
The original bridge posts and thumbwheels were nickel plated brass and the reissues are nickel plated steel.

Awesome. Thank you very much.

sounds like Gibson got the reissue stuff backwards. lol.

Substituting steel for brass and brass for steel will make a difference acoustically. They have rather different elastic moduli and densities.

Interested by the lead content, quite a common thing to improve machinability, especially for CNC. I take it someone's been doing some XRF or EDS/EDX analysis...

Probably doesn't make much difference to an acoustic wave, but then who knows.
